"ST. LOUIS, Mich. – Jim Hall was mowing the town’s baseball diamond when he felt a little bump underneath him. “And there it was, a dead robin,” he said.

Just last week, he found another one. “Something is going on here,” said Hall, who has lived in this mid-Michigan town of 7,000 for 50 years.

Two dead birds may not seem like much. But for this town, it’s a worrisome legacy left behind by a chemical plant-turned-Superfund site.

After residents complained for years about dead birds in their yards, 22 American robins, six European starlings and one bluebird were collected for testing.

The results, revealed last week: The neighborhood’s songbirds are being poisoned by DDT, a pesticide that was banned in the United States more than 40 years ago. Lethal concentrations were found in the birds’ brains, as well as in the worms they eat."
